Title: Exciter for power generator
Inventor: SHIBUYA AKIRA
IPC: H02P9/08
Filed: 1980-03-07
Abstract: PURPOSE:To reduce the capacity of a drive unit and to decrease the amount of used electric power by generating a peak voltage in response to the energy dissipating pattern when a generator produces energy to a load and setting the exciting output at zero at the time of reaccelerating the generator after the energy is produced. CONSTITUTION:When a generator reaches the maximum speed at (t1) after it is started and accelerated, an exciting current I1 responsive to the energy dissipating pattern is immediately applied thereto at (t3). After the generator dissipates the energy, a reverse current is applied thereto, and thus the voltage at the terminal of the generator is set abruptly at zero, and the output of the exciter is thus set at zero. When the rotating speed of the generator is again accelerated at (t4), it may prepare only a drive unit for the loss corresponding to the mechanical loss to thus reduce the capacity of the drive unit and to reduce the power consumption.

Title: Cylinder block of water cooled type internal combustion engine
Inventor: NODA KOJI
IPC: F01P3/02
Filed: 1993-02-18
Abstract: PURPOSE:To speed up flow of cooling water along a joining recessed part so as to improve heat radiation effect by forming the width of a water jacket in a smaller size on the downstream side near the joining recessed part than that of an upstream side in a cylinder block formed by joining adjacent cylinder walls with each other and having the joining recessed part between the adjacent cylinder walls. CONSTITUTION:In a Siamese type cylinder block 1, adjacent parts in four cylinder walls 2 which are aligned in series are joined with each other so as to shorten the total length of an engine. A water jacket 3 for circulating cooling water is provided around each cylinder wall 2, and it is partitioned by a water jacket wall 4 for enclosing the cylinder wall 2. A joining recessed part 6 is formed between the adjacent cylinder walls 2. In this case, the flow passage width Mb of the water jacket 3 which is faced to the bottom part of the joining recessed part 6 is formed smaller than the flow passage width Ma of the water jacket 3 which is faced to the upper part of the joining recessed part 6. It is thus possible to speed up flow of cooling water passing through the joining recessed part 6 so as to improve heat radiation performance in that part.
